Which of what? What’s the rest
People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected. High blood sugar impairs the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>
Answer: The science of naming and classifying organisms based on structural comparisons and genetic evidence, is known as taxonomy, a branch of biology.
Explanation: Taxonomy is very important. By categorizing organisms, this branch of biology helps scientists to exchange vital biological information, and therefore understand the diversity of species in our planet.
